本発明は、屋根の軒先における修めを構成する鼻隠し材であって、軒先に容易に装着することができ、且つ通気性が良好であると共に雨水の浸入を防止することができる換気機能付き鼻隠し材に関する。 The present invention is a nasal cover material that constitutes repairs at the eaves of a roof, can be easily attached to the eaves, has good ventilation, and prevents intrusion of rainwater. Concerning hidden material.

一般に、屋根の軒先には、垂木を覆う鼻隠し材が装着されている。この種の鼻隠し材として、代表的なものとして、特許文献１に開示されている。この特許文献１に開示されたものは軒先構造が鼻隠し材と軒先水切り板とから構成されている。
特開平７−３４５５９号 Generally, a nose cover material that covers rafters is attached to the eaves of the roof. As this kind of nose masking material, it is disclosed by patent document 1 as a typical thing.

JP 7-34559 A

ところで、従来の軒先構造では、軒先水切り板部に多数のスリット状の換気孔が形成されている。この換気孔は、軒先水切り板部の正面側に形成されたことにより、外部の空気を取り入れ易い構造となっているが、風雨時には、雨水が前記換気孔に直接入り込んでしまうおそれが十分にある。このような不都合を解消することが特許文献１に開示されている。この特許文献１では、換気孔を軒先水切り板部の正面側に形成しないで、底面或いは背面側に形成することにより、直接、雨水が浸入し難いような構造にすることもできる。 By the way, in the conventional eaves tip structure, many slit-shaped ventilation holes are formed in the eaves tip draining plate part. Although this ventilation hole is formed on the front side of the eaves edge draining plate portion, it has a structure that allows easy intake of external air, but there is a sufficient risk that rainwater may directly enter the ventilation hole during wind and rain. . Patent Document 1 discloses that such inconvenience is solved. In this patent document 1, it can also be set as the structure where rain water does not enter directly by forming a ventilation hole in a bottom face or a back side, without forming it in the front side of an eaves edge draining board part.

このような構造は、複雑で据付も面倒となり、施工技術が未熟な作業員による施工の場合には、前記鼻隠し材と前記軒先水切り板との連結箇所の防水性が不十分であったり、或いは軒先水切り材が複数の部品から構成されているために、その組付けが不十分である場合にはやはり防水性に問題が生じることになる。そこで、本発明が解決しようとする課題（技術的課題又は目的）は、軒先への装着を極めて簡単なものとし、且つ装着完了後においても換気性と共に防水性等を極めて良好なものにすることを実現することにある。 Such a structure is complicated and troublesome to install, and in the case of construction by an unskilled worker, the waterproof property of the connecting part between the nasal covering material and the eaves draining board is insufficient, Alternatively, since the eaves draining material is composed of a plurality of parts, if the assembly is insufficient, there will still be a problem in waterproofness. Therefore, the problem (technical problem or purpose) to be solved by the present invention is to make it very easy to attach to the eaves, and to make the waterproof property and the like very good even after the completion of the attachment. Is to realize.

本発明の第２実施形態における遮蔽部３（山形遮蔽部３３）では、図４（Ｅ）に示すように、前記高位置３３ａから低位置３３ｂ，３３ｂに向かって円弧状傾斜面又は直線状傾斜面となり、雨水が遮蔽部３上に溜まることなく、その両側から即座に雨水を落下させることができ、雨水がより一層、換気孔２から浸入しにくい構造にすることができる。図４（Ｅ）において、太い矢印は雨水の流れを示すものである。また本発明の第３実施形態では、特に図示しないが、前記遮蔽部３の山形遮蔽部３３は、前記前面板部１１の裏面側に膨出形成されることもある。図４（Ｃ）において、太い矢印は空気の流れを示すものである。 In the shielding part 3 (mountain shielding part 33) in the second embodiment of the present invention, as shown in FIG. 4 (E), an arcuate inclined surface or a linear inclination from the high position 33a toward the low positions 33b and 33b. As a result, the rainwater can be immediately dropped from both sides thereof without collecting the rainwater on the shielding part 3, and the rainwater can be further prevented from entering from the ventilation hole 2. In FIG. 4 (E), thick arrows indicate the flow of rainwater. In the third embodiment of the present invention, although not particularly illustrated, the mountain-shaped shielding part 33 of the shielding part 3 may be formed to bulge on the back surface side of the front plate part 11. In FIG. 4C, a thick arrow indicates an air flow.

本発明の第３実施形態は、前記遮蔽部３を、図６に示すように、前記換気孔２の内周縁の一部から傾斜状に折り曲げ形成された折曲遮蔽部３４としたものである。該折曲遮蔽部３４は、単に前面板部１１の一部を折曲形成したものであり、前記遮蔽部３を最も簡単に形成することができるという利点がある。折曲遮蔽部３４は、前記前面板部１１（又は底面板部１２,背面板部１３）の表面（筐体状部１の外方側）、或いは前面板部１１（又は底面板部１２,背面板部１３）の裏面（筐体状部１の内方側）のいずれにも形成することができる。 In the third embodiment of the present invention, as shown in FIG. 6, the shielding portion 3 is a bent shielding portion 34 that is bent from a part of the inner peripheral edge of the ventilation hole 2 so as to be inclined. . The bent shielding part 34 is simply formed by bending a part of the front plate part 11 and has an advantage that the shielding part 3 can be formed most easily. The bending shielding part 34 is a surface of the front plate part 11 (or the bottom plate part 12 and the back plate part 13) (outside of the housing-like part 1), or the front plate part 11 (or the bottom plate part 12, It can be formed on any of the back surfaces of the back plate portion 13) (inward side of the housing-like portion 1).

本発明の鼻隠し材の装着は、図７（Ａ）に示すように、まず建築構造物７の軒先箇所の上部において屋根を構成する屋根板７１と野地板７２との間に取り付けられたジョイント部材７５に前記鼻隠し材の正面接続端片が係止固定される。また前記鼻隠し材Ａの後部接続片６が建築構造物７の軒桁７３の下部に装着される。このように、鼻隠し材において、前記筐体状部１は、正面主板部５及び後部接続片６と一体的に形成されているので、鼻隠し材Ａの前方側と後方側の２箇所のみが建築構造物７の軒先箇所を介して接続するのみで、最小限の工程にて、極めて簡単に施工することができる。また、前記背面板部１３の上方に軒先天井板７４が設置されるものである。 As shown in FIG. 7 (A), the nose masking material of the present invention is a joint first attached between the roof board 71 and the field board 72 constituting the roof at the upper part of the eaves portion of the building structure 7. The front connection end piece of the nose masking member is locked and fixed to the member 75. Further, the rear connection piece 6 of the nose masking material A is attached to the lower part of the eaves girder 73 of the building structure 7. Thus, in the nasal concealment material, since the housing-like part 1 is formed integrally with the front main plate part 5 and the rear connection piece 6, there are only two places on the front side and the rear side of the nasal concealment material A. However, only by connecting through the eaves part of the building structure 7, construction can be performed very easily with a minimum number of steps. Further, an eaves ceiling board 74 is installed above the back panel 13.

図１及び２には、別の実施形態が示されている。各換気孔２は、長孔であり、上下方向の長手方向に延びるスリット形状，筋形状としたものである。そして、各換気孔２の大きさは、適宜の寸法とする。具体的には長さは好適な寸法とし、幅は約３mm程度であり、各換気孔２，２同士の間隔は約３mm程度が好ましい。前記換気孔２には、遮蔽部３が一体成形されている。該遮蔽部３は、換気孔２の内周縁２１の一部の２箇所と連続し、且つ前記前面板部１１から前記換気孔２の孔領域２１ａ側に向かって（すなわち、孔領域２１ａ内に向かって）前記内周２１の一部の２箇所以外は切り込まれた断面略皿形状に膨出形成される〔図１（Ｄ）,図２（Ｂ）参照〕。 1 and 2 show another embodiment. Each ventilation hole 2 is a long hole, and has a slit shape and a streak shape extending in the longitudinal direction in the vertical direction. And the magnitude | size of each ventilation hole 2 shall be an appropriate dimension. Specifically, the length is a suitable dimension, the width is about 3 mm, and the interval between the ventilation holes 2 and 2 is preferably about 3 mm. A shielding part 3 is integrally formed in the ventilation hole 2. The shielding part 3 is continuous with two portions of the inner peripheral edge 21 of the ventilation hole 2 and is directed from the front plate part 11 toward the hole area 21a of the ventilation hole 2 (that is, in the hole area 21a). The other part of the inner periphery 21 is formed in a substantially dish-shaped cross section, which is cut out (see FIGS. 1D and 2B).

前記換気孔２の孔領域２１ａの一部においては、該孔領域２１ａは、前面板部１１の換気孔２と前記遮蔽部３に囲まれた部分となっている。すなわち、前記換気孔２の孔領域２１ａとは、前記前面板部１１（又は底面板部１２及び背面板部１３）の換気孔２の内周縁２１と前記遮蔽部３に囲まれた貫通孔の部分のことである〔図１（Ｄ）等参照〕。つまり、前記換気孔２と前記遮蔽部３の開口部は、異なる断面形状となる。前記遮蔽部３は、前記前面板部１１,底面板部１２及び背面板部１３の少なくともいずれか一つの部分において、その裏面側もしくは表面側に形成されることになる。 In a part of the hole area 21 a of the ventilation hole 2, the hole area 21 a is a part surrounded by the ventilation hole 2 and the shielding part 3 of the front plate part 11. That is, the hole region 21 a of the ventilation hole 2 is a through hole surrounded by the inner peripheral edge 21 of the ventilation hole 2 of the front plate portion 11 (or the bottom plate portion 12 and the back plate portion 13) and the shielding portion 3. It is a part [see FIG. That is, the ventilation hole 2 and the opening of the shielding part 3 have different cross-sectional shapes. The shielding part 3 is formed on the back side or the front side of at least one of the front plate part 11, the bottom plate part 12 and the back plate part 13.

そして、前記換気孔２と前記遮蔽部３とによって、開口部４が形成される。該開口部４は、前記換気孔２の断面形状とは異なる断面形状を有する〔図２（Ａ），（Ｂ）参照〕。該開口部４は、前記換気孔２と連通するものであり、前記遮蔽部３は前記換気孔２の一部を離れた位置から覆うようにして、換気孔２の一部を遮蔽する役目をなす。すなわち、前記遮蔽部３は前記換気孔２を閉鎖するものではなく、換気孔２の内周２１の２箇所が残され、前記遮蔽部３によって換気孔２の内周２１の２箇所の他に開口部４が設けられるものである。 An opening 4 is formed by the ventilation hole 2 and the shielding part 3. The opening 4 has a cross-sectional shape different from the cross-sectional shape of the ventilation hole 2 (see FIGS. 2A and 2B). The opening 4 communicates with the ventilation hole 2, and the shielding part 3 serves to shield a part of the ventilation hole 2 by covering a part of the ventilation hole 2 from a remote position. Eggplant. That is, the shielding part 3 does not close the ventilation hole 2, and two places of the inner periphery 21 of the ventilation hole 2 are left. In addition to the two parts of the inner periphery 21 of the ventilation hole 2 by the shielding part 3, An opening 4 is provided.

前記遮蔽部３は、図１，図２に示すように、前記換気孔２の長手方向を上下方向に一致させ、該換気孔２における長手方向（上下方向）両側の内周縁から略扁平門形状の帯形状遮蔽片３１を前記前面板部１１（又は底面板部１２,背面板部１３）から膨出形成されたものである。該帯形状遮蔽片３１は、前記換気孔２の長手方向に沿って、換気孔２の孔領域２１ａの一部を覆うようにして前記前面板部１１（又は底面板部１２,背面板部１３）から膨出形成されたものである。該帯形状遮蔽片３１が形成される換気孔２の形状は略長方形状であり、帯形状遮蔽片３１は、前面板部１１の正面より見て長方形状となる。前記帯形状遮蔽片３１の幅方向両側と換気孔２（の孔領域２１ａ）との間に形成される隙間が開口部４となる。 As shown in FIGS. 1 and 2, the shielding part 3 has a substantially flat gate shape from the inner peripheral edges on both sides in the longitudinal direction (vertical direction) of the ventilation hole 2 such that the longitudinal direction of the ventilation hole 2 coincides with the vertical direction.
